| | BIOQUAKE IN THE BERING SEA (Site not responding. Last check: 2007-10-20) |
 | | During winter gales, when the mixed layer reaches its maximum depth of 200m, the shallower regions of the Bering Seas are enriched by nitrogen, phosphorus and silica dredged from deeper regions by strong currents. |
 | | The shallow depth of much of the Bering Sea makes its ecosystem unusually sensitive to climatic fluctuations, and in 1997, a combination of events sent its climate and biology "crazy", according to Dr Robert Francis, a fisheries oceanographer of the University of Washington, Seattle. |
 | | Researchers in the Bering Sea watched the shearwaters increase the amount of fish in their diet to a level not previously recorded, to compensate for the lack of krill. |
